I do sometimes think we get too hung up on the detail rather than just getting on with the job. However, if the decision has been made not to publish the recording, I'd certainly not publish half the meeting recording; that's just nonsensical. Either do it or don't do it but I'd personally retain it should there be a request for it by a member of the public at a later date. Thereafter, I would stick to whatever decision has been taken with regard to the actual recording of meetings going forward and ensure there is an appropriate policy with regard to retention of any recording thereafter.
As for the public participation session, the decision was taken to change this from the next meeting. You therefore have your action as agreed for that particular resolution.
